Answer 2

Hello mate..

Here Is Your Answer:

GIVEN:

• Radius (r) = 2.8 cm
• Height (h) = 12 cm
• pi (π) = 22/7

TO FIND:

Volume of the cone with the given measurements.

SOLUTION:

$\rightarrow \bold \pink{volume \: of \: a \: cone \: = \frac{1}{3} \times \pi {r}^{2} h}$

$\implies \rm{ \frac{1}{3} \times \frac{22}{7} \times 2.8 \times 2.8 \times 12} \\ \rm{ = 22 \times0.4 \times 2.8 \times 4} \\ \rm{ =22 \times 1.12 \times 4 } \\ \rm{ = 98.52}$

Therefore, volume of the cone is 98.52 cm³.

HOPE THIS HELPS YOU..

THANKS..!!
